How do I receive data sent by Heart rate service app to nRF52840 board?

[Mathangopal]

Hi. I am currently using the nRF52840 DK board and using the SDK 17.02.

There is our software engineers who are working on the heart rate service app to modify to suit our requirements.

One of the requirements is to receive commands and data.

I want to know how to receive data sent by Heart rate service app to nRF52840 board?

Thank you. I will appreciate the help.

Hi

What heart rate service app is this exactly? Are you using a phone and the nRF Toolbox or nRFConnect apps for example? Will the nRF52840 board be used as a central or peripheral in this usecase? I would suggest checking out our BLE Heart Rate Service examples available in our SDK. Please check out this link for a central example project, and this link for a peripheral example.

Best regards,

Simon

Hi. I am currently using the nRF Connect mobile app.

The board is used as a peripheral. Currently, I am using the BLE Heart rate service example and modified to add a characteristic to heart rate service. It is able to write data to the nRF52840 DK. How do I change the name of the characteristic which is named as "Unknown Characteristic"?

Thank you.

Hi

Have you checked out our BLE characteristics tutorial, which explains step by step how to add characteristics and define/configure custom characteristics as you want them in your application.

Best regards,

Hi. Yes I have.

I know how to change my characteristic name base on the thread below;
